MULTIPLE-SOCKET INSERT FOR CONCRETE WORK.

Application filed May 31, 1927. Seria1 No.-195,208.

The present invention relates to devices for use in concrete or masonry construction, and the primary object in view is to provide a simple and improved insert member or anchoring socket designed tobe embedded in the concrete or mortar inthe course of construction, and for functioning as means for attachment of construction materials to'the exterior face of the concrete or motar through the medium of driven fastenings entering the sockets of Said insert devices. I

Accordingly, I have devised an extremely simple and inexpensive element of this character adapted to be embedded in the concrete or like material and aflordone or more sockets flush with the face of the structure,'whereby drivenfastenings maybe applied to such sockets and'be thereby securely held by firm frictional engagement in permanent relation to the surface of the structure.

Preferably, I have embodied the invention in an improved insert device adapted to be temporarily held by a form member upon the removal of which the insert member is left behind in its permanent embedded relation to the concrete or masonry structure.

lVith these general objects in view the invention will now be described by reference to the accompanying drawings illustrating one 'form of construction which I have devised for embodying the proposed improvement, after which those features deemed to be novel will be particularly set forth and claimed.

In the drawing Figure 1 is a perspective view of a device embodying the present invention;

Figure 2 is a plan view of one side of the same;

Figures 3 and 4 are end and side edge views, respectively, of the device;

Figure 5 is a perspective view of a portion of a form member and concrete structure showing the method of embedding the device in position for use; and

Figure 6 is a similar perspective view illustratin g the mode of securing a corner bead or plaster ground by means of the improved device.

Referring to the drawing in detail, this illustrates my improved insert device as constructed of sheet material such as corrugated metal having crimps or corrugations 10 and cut into sections of any desired size which are folded along a middle line transverse of the corrugations, so that the latter cooperate to form a row or series of recesses 12 ofwell defined and approximately semi-circular gross section, all as clearly shown in Figures- These devices are designed to be installed in l the face of the concrete structure, such as indicated at 14 inFigures 5 and 6, where they may be placed'by hand asthe construction proceeds if desiredBut I prefer to locate them by temporary attachment to'the form work, forwhich purpose any suitable expedient may be employed, Figure 4 showing the device. as punched with an opening 15 fora nail 16 for securing the device to the'inner face of one of the form members 17 as shown in Figure 5, or the device may be'form'ed with prongs or spurs 18 forthis purpose. In this way the device may be secured in place with the mouths of the recesses 12 in position to come flush with the face of the concrete surface 14, and hence become permanently anchored in this position after the removal of the form members 17. Unless used for attaching any exterior strips or finishing to the concrete, the points of the nails 16 may simply be bent over or clinched into the face of saidconcrete material.

Having installed in the course of construction the proper number of the devices, according to requirements, it is apparent that they are now adapted to afford an attaching or securing function by means of the recesses or sockets 12, into which may be driven from the exterior any suitable fastenings, such as nails 20 or the like, for applying any desired construction work such as grounds, screeds, molding, expanded metal, etc., to the exterior surface of the concrete. For example, reinforcing material, or a corner bead, or molding 22, may be efliciently secured in the position illustrated in Figure 6 by means of the nails 20, and in view of the anchoring inserts providing a plurality of the sockets 12, this affords a greater range for driving the nails at the proper points for securing an accurate or correct alinement of the bead or roll 22 of such moldings with the corner line or edge 14 of the concrete structure.

The described construction of the openings or recesses 12 produces a substantially cylindrical socket adapted to embrace practically all sides of the nail or equivalent fastening 20, and hence efficiently grip such fastoning and hold it by secure frictional engagement within the socket.

The improved device is of strong, simple and inexpensive construction, adapted to be manufactured economically, and, is readily understood, is very easy and convenient to install.

\Vhile I have illustrated and described what I now regard as the preferred form of construction for embodying my invention, I desire to reserve the right to make all such changes or modification as may fairly fall Within the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A socket insert for concrete or masonry work comprising a metal element adapted to be embedded in the concrete or masonry material and formed of sheet metal folded to produce mating semi-cylindrical recesses cooperating to form a substantially cylindrical pas sage extending at right angles to and having one end exposed at the face of said material, and adapted for frictionally retaining a driven fastening.

2. A multiple socket insert for concrete work comprising a device adapted to be anchored in the concrete and formed of sheet metal folded and crimped to provide a plurality of mating semi-cylindrical recesses cooperating to form substantially cylindrical passages extending at right angles to and having one end of each passage exposed at the face of the concrete structure and each. passage adapted for frictionally securing a driven fastening.

3. A multiple socket insert for concrete work comprising a device adapted to be anchored in the concrete and formed of sheet metal folded and crimped to provide a plurality of mating semi-cylindrical recesses cooperating to form substantially cylindrical passages extending at right angles to and having one end of each passage exposed at the face of the concrete material and each passage adapted for frictionally securing a driven fastening, the folded margin of the device being provided with a nail opening registering with one of said passages for accommodating a nail in temporarily securing the device to a form member.

In witness whereof I hereunto ailix my sig nature.
